Description

Technical Field

[0002] Most existing blow molding machines use a plastic chain-push mechanism with a rectangular chain track and a standard heating lamp box. The lamps are arranged on one side of the preform, resulting in high energy consumption, a limited number of heating positions, and uneven heating of the preform; they also occupy a large area. Therefore, new, high-efficiency blow molding machines have emerged on the market, such as the Chinese utility model patent CN202221694183.8, which specifically discloses a frame, chain track mechanism, preform loading mechanism, reversing stepping mechanism, lamp box heating mechanism, mold closing and stretching mechanism, hand-operated pitch-changing mechanism, and bottle unloading stepping mechanism. Although this patent provides a reversing stepping mechanism, it uses a large gear for steering, resulting in a large turning radius, long preform drying time, and many ineffective chain track positions, significantly reducing work efficiency and increasing energy consumption.

[0009] Preferably, the inverted bottle blank is placed above the bottle blank seat.

[0010] Preferably, the lower part of the connection between the blank track and the longitudinal double track is fixedly connected to the rack table top through the track support seat.

[0011] Beneficial effects:

[0012] The bottle blank seat is pushed into the turning mechanism through the chain track stepping mechanism, and is driven by the servo motor reducer, so that the entering bottle blank seat rotates 180 degrees with the turntable driven by the servo motor reducer, rotates from the left stepping track into the right stepping track, and realizes the turning-back movement.

[0013] Moreover, the device has the characteristics of small floor space and rapid turning. BRIEF DESCRIPTION OF DRAWINGS
